LORCA, a town of eastern Spain, in the province of Murcia, on World: the Grandeur and Failure of Civilization (1867); Ancient the right bank of the river Sangonera (here called the Guadalantin
or Guadalentin) and on the Murcia-Baza railway. Pop. (1900) 69,836. It occupies a height crowned by a medieval fortress, among the foothills of the Sierra del Calico. Its older parts, Moorish in many features and with narrow irregular streets, contrast with the modern parts, which have broad streets and squares, and many fine public buildings—theatre, town hall, hospitals, courts of justice and a bridge over the Sangonera. There is an important trade in agricultural products and live stock, as well as manufactures of woollen stuffs, leather, gun-powder, chemicals and porcelain. Silver, sulphur and lead are found in the neighbourhood.
Lorca is the Roman Eliocroca (perhaps also the Ilorci of Pliny, N.H. iii. 3) and the Moorish Lurka. It was the key of Murcia during the Moorish wars, and was frequently taken and retaken. On the 3oth of April 1802 it suffered severely by the bursting of the reservoir known as the Pantano de Puentes, in which the waters of the Sangonera were stored for purposes of irrigation (1775–1785); the district adjoining the river, known as the Barrio de San Cristobal, was completely ruined, and more than six hundred persons perished. In 1810 Lorca suffered greatly from the French invasion. In 1886 the Pantano, which was one of the largest of European reservoirs, being formed by a dam Boo ft. long and 16o ft. high, was successfully rebuilt.
